BY I ywm ATTORNE Patented Apr. 15, 1930 HERMAN MAYER, OF PHILADELPHIA, PENNSYLVANIA REFLECTOR Application filed April 9, 1929. Serial no. 353,873.

My invention relates to a new and useful reflector which is particularly adapted for use in industrial establishments for the purpose of shielding or protecting the eyes of 5 workmen operating any given machinery from the direct glare of the lightsilluniinatingsaid machinery, and which at the same time will effectively illuminate such machinery thereby raising the standard of efficiency.

My invention further relates to a reflector of this general character, the novel construction of which causes the rays of light to be repeatedly reflected and deflected to produce a uniform diflusion of light to provide a soft 15. light.

My invention further relatesto a reflector of this character the novel construction of which lends itself to adjustment to any desired angle for use in connection with any de- 20 sired machinery, my novel reflector being provided with novel adjustable supporting devices.

My invention further relates to a reflector which while efficient and durable, also possesses an attractive appearance, is easy to manipulate, and is inexpensive to produce.

The invention consists of the novel construction hereinafter described and finally claimed.

Forthe purpose of illustrating my invention I have shown in the accompanying drawings formsthereof which are at present preferred by me, since the same havebeen found in practice to give satisfactory and f5 reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously Fig. 2.

Figs. 8, 9 and 10 represent fragmentary top plan views showing further modified constructions of the top of my novel reflector shown in Figs. 1 to 6.

Figs. 11, 12, and 13 represent sectional views on lines 1111, 12-12, and 1313, of Figs. 8, 9, and 10 respectively.

Figs. 14, 15, 16, 17, and 18 represent Various arrangements for supporting my. novel reflector in operative position with respect to the object to be illuminated.

Referring to Figs. 1 to 4: of the drawings, in which drawings similar numerals of reference indicate corresponding parts, 1 designates a reflector embodying my invention comprising a substantially cylindrical shell or casing 2 provided with thebottom outwardly anddownwardly flaring side walls 3. To the top of the cylindrical member 2 is suitably secured the trough shaped member 4: composed of the upright longitudinal walls 5 having the bottom flanges 6 which may be soldered, spot welded, or riveted to the top of the cylindrical shell 2, and with the upper, outwardly deflected flanges 7 which engage the bent edges 8 of the sliding top or cover 9. The. upright longitudinal walls 5 of the trough shaped member 4 are joined at their ends by the end walls 10 having the upper reinforcing flanges 11, and with the upper cross braces 12, having the flanges 13, which are suitably secured to the upper portion of the longitudinal walls 5. The cross braces 12 are suitably spaced from the upper ends of the walls 10 to form the openings 14 for the entry of the electrical conductors 16 leading to the electric socket17 which supports an electric light 18. The electric socket 17 is adapted to pass through an opening 19 in the top portion of the cylindrical shell 2 (see Figs. 2 and 3) and is provided with the bottom enlarged portion 20 and the top cylindrical portion 21.

The cylindrical portion 21 of the socket 17 carries the ring or annular band 22 provided with the threaded deflected eyelets 23 which receive the screws 24. The band 22 carries the fingers 25 which are adapted to engage the notches or shoulders 26 at opposite points of the outer surface of the cylindrical member 21, so that when the screws 24 arethreaded in the eyelets 23 and the bottom ends thereof bear against the top of the shell 2, the band 22 is forced upwardly with respect to the socket 17, thereby forcing the fingers 25 into engagement with the shoulders 26 to retain the socket 17 against downward displacement. When it is desired to remove the socket 17 the screws 24 are unthreaded from the eyelets 23 whereupon the band 22 is permitted to drop to permit the disengagement of. the fingers 25 from the notches 26 and the band 22 is then slipped over the upper end of the cylindrical member 21 and the socket 17 is withdrawn inwardly or downwardly through the aperture 19 in the top of the shell or casing 2. 30 designates a switch comprising the frame or support 31 which carries the stationary contact member 32 and the movable spring pressed contact 33 which latter is operated by the externally projecting knob or push button 34 to make or break the electric circuit energizing the electric bulb 18. The shell 2 is provided with the end walls 36 the bottom ends of which are rearwardly inclined as at 37 and which are provided with the inwardly extending sleeves 38 adapted to receive supporting fingers or journals (not shown). which are engaged by the set screws 39 for retaining the reflector 1 in a desired angular position with respect to said supports. The sleeves 38 may be formed integral with the end walls 36 or if desired they may be formed of the same material as that from which the reflector is and may be riveted, soldered, or spot welded to the end walls 36 in any suitable manner.

In Fig. 5 I have illustrated a reflector 1 of the identical construction illustrated in Figs. 1 to 4, except that the shell or casing 2 is polygonal, the same being composed of the sides 40, 41, 42, 43, 44, 45, 46, and 47, and the end walls 36 terminating in the bottom upwardly and rearwardly inclined bottom edge 37, this particular form of the shell or reflector 2 being preferred in certain cases where a highly diffused soft light is desired since the angularly disposed sides 40 to 47 of said shell tend to increase the reflection and deflection of the rays of light emanating therefrom. In lieu of the upper end walls 10 of the trough shaped member 4 I employ the end walls 49 having the apertures 50 for the reception of the electrical conductor 16.

In Fig. 6, I have shown a further modification of my invention wherein the shell 2 i is of a substantially parabolic form in contradistinction to the cylindrical form of said shell illustrated in Fig. 1.

In Fig. 7 I have illustrated a novel I11t11- ner of fastening or securing the top 51 (shown in Fig. 1 and 2) the same being hinged to one of the upright walls 5 as at 52 at one side thereof and being adapted to be secured to the other of said upright walls 5 by the pin 53 which is adapted to engage the apertured lugs 54 on said upright wall 5 which are adapted to register with a ccntrally disposed apertured lug 55 carried by said cover member. This hinged form of cover may, if desired, be substituted for the sliding cover 9 illustrated in Figs. 1 and 2. In Fig. 8 I have illustrated a further modification of my invention wherein in lieu of the hinged cover 51 or sliding cover 9 I cmploy a permanently secured cover 56 provided with the aperture 57 registering with the socket- 17. said aperture 57 being closed by the plate 58 which is secured to the permanent cover 56 by the screws 59. In Fig. 9, I have illustrated a further modification of my invention wherein I employ a permanent cover60 provided with the grooves or tracks 61 in which is adapted to slide the cover 62 which is operated by the handle 63. In this construction the cover 62 is withdrawn by pulling the handle 63, thus affording access to the socket 17 and its adjuncts.

In Fig. 10, I have illustrated a further modification of my invention wherein I employ a permanent cover 60 and a sliding cover 62 provided with a handle 63 except that the grooves or tracks 61 are formed along the edge of the sliding cover 62 and are adapted to engage the pro ecting ends of the permanent cover 60 the construction shown in Fig.

10 being the reverse of that shown in Fig. 9.

In Fig. 14 I have illustrated a manner of supporting my novel reflector with respect to a machine generally designated by the numeral 65, the reflector 1 being carried by the ournals 67, which pass through the sleeves 38 and are engaged by the set screws 39, said journals being pivoted to the forked upper end 68 of the arm 69 which is suitably bent as at 7 O and which is secured at its lower end to a suitable part of the machine 65 as at 71.

In Fig. 15, I have illustrated a diflerent manner of supporting my novel reflector which consists in providing the pendant links 72 pivoted to the upper forked end 68 of the arm 69 and having their lower ends deflected inwardly to form journals which are adapted to engage the sleeves 38, said journals being engaged by the set screws 39. The arm 69 is secured to the machine 65 as at 71 in the same manner illustrated in Fig. 14. I have illustrated another manner of supporting my novel reflector which is identical with that described in Fig. 14 except that the arm 69 in lieu of bein secured to a part of the machine 65 as in igs. 15 and 14, is

In Fig. 16,

secured to a suitable support 74 on the floor 75 alongside, in front, or behind the machine but independently thereof.

In Fig. 17, I have illustrated the manner of supporting my novel reflector in a pendant or suspended position, the arm 69 being secured at its upper end to the ceiling 76 so that the rays of light from the reflector 1 are directed upon the machine 65 as shown.

In Fig. 18, I have illustrated a manner of supporting a plurality of my novel reflectors from a common support 77, which is carried by the uprights 78 which are secured to the machines 65 as at 71, or which may be suspended from the ceiling 76 or supported directly upon the floor at will.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present em bodiment to be considered in all respects as illustrative and not restrictive, reference be ing had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

While I have illustrated the use of a single electric socket 17 for supporting a single light 18, it is to be understood that a plurality of lights may be employed if so desired, which may be carried by one or a plurality of sockets.

As shown in Fig. 3, the interior of my novel reflector is corrugated vertically and is provided with a plurality of diamond-shaped surfaces formed by the intersections of oblique planes, thus affording an effective reflecting surface which breaks up the rays of light to produce a highly diffused bright light.

Having thus described my invention, what I claim is new and desire to secure by Letters Patent, is
